CQL Under the Hood by Robbie Strickland.
As a reformed CQL critic, I’d like to help dispel the myths around CQL and extol its awesomeness. Most criticism comes from people like me who were early Cassandra adopters and are concerned about the SQL-like syntax, the apparent lack of control, and the reliance on a defined schema. I’ll pop open the hood, showing just how the various CQL constructs translate to the underlying storage layer–and in the process I hope to give novices and old-timers alike a reason to love CQL.
